Bet known that I, WELLINGTON P. K11) oston, in the county of SufiolkiandState of Massachusetts, have invented certain new and useful Improve-Shifting Mechanism'ior' ments in Carrie which the following is a.

Type-Writers, fill clear and exact descri tion, such as will 7 enableothers skilled in t eart towhich it ap ertains to'm-ake and use thesame.

As ':tending to render clearer certain of the various general'featuresof my invention, it mayhere be noted that, in typewriters wherem a smallnumberof keys are employed,

the arrangement offthe printing devices 111 groups, it is necessa toprovide mechanism adapted v to shift tlie same to several positions inorder to employ a. printthe several groups. I have', therefore, found itdesirtype to probe shifted silentl initial position'ss e ebore'an Motheradvanlent'ii typewriters, andhas for one ofitsobabove type will-operatewithout ,1S- in engagement with -t dashpot 9, :as hereinbeforeexplained, lock osi'tion to other tages are secured in constructions ofthe nature of that hereinafter described. I

Referringnow' tothe drawings, a. vertically reciprocating carriage 1 hassecured therete a channel bar 2 in which is slidably mounted ablook 3.Double rocker arm 4 pivoted at 5i'to bracket 6 carried by the frame 015the machine .ispivotall'y' attached at one enrl to block 3- and at itsopposite end to piston rod 1 which isadapted to carry piston-8 workingin dfish'pot. .f When the carriage I is in initial position, assh'own'in the drawings,- piston 8 is in engagement with the bottowall ofdashpot 9. Piston lower member 10 mounted in piston 8 and has its upper'en split and internally threaded to engage with member ll andexrernall'ythreaded tocarry lock nut 12;

Members 10 and. 1'1 aretherefore capable 0t rod '7'- epmprises aPatented March 24, 19081, a

adjustmentin order toshorten orlengthmr piston rod 7, thereby operatingto determ'me the position of the earria 1 when piston 8- bottom. wall ofnut 12 operating tomaintainfmembe rs- 10 and 11 infixed adjustment.

' To the opposite end oi rocker lever 4- there 7 is pivotally tta'chedat 13 an adjustable" piston rod 14 constructed similarly to piston Y rod7 above described, which" carries at its lower end piston 15 operatingin dashpotllfii Dashpot 16 is carried: by an arm 17, pivoted naledthereon at 19 adapted norm-ally to rest odasliding cam 20, as clearlyshown in Fig. 3 of the drawings. Sliding cam 20 rest-- ingon guideroller 21 to bracket 6 and carries scam roller 18 jourv ournaledto'a-stuxi 22 Y positioned upon the rame .of' the machine,

extends between flange 23 and stud 22 and is adapted to be reeiproeatedend'wise by shift lever 24 'onrnaled on key lever shaft 25 acting thronglink-26 ivo-tally connected at one end to arm 27 oi shift lever 24' andat its opposite end -,to hell crank lever 28 pivoted to the frame of themachine at 29 and tohwhieh sliding tached' .at 30. Link: 31 is pivotal]conver'35 is carried uponvrock shaft 34 andis cam '20 is pivotally atneeted atone end to double rocker ever 4 at 32 and at its opposite endto lever 33 positioned zupon rock shaft 34. Forked logdapted begactuatedla) agrln 36 carried ymova e a utment 37 y 'tioncd upon key lever shaft2.5 journal g is the frame of the machine. Arm 36 is provided with aball 38 engaging between the mem- 'bers 39 and 40 of forked lever 3-5,thereby constituting a universal connection thereuniversal connectiontherewith, such movement being communicated through'arm 33 and link 31to double rocker arm 4, to shift the carriage 1 and cause piston 15 tobe pro-,

'jected downwardly in dash pot 16, the im- Tbe accurately determined,inasmuch as theprisoned air therein forming a cushion, therebyyieldingly resisting such move ment and causing piston 15 to silentlyimpinge against the bottom wall of dash pct 16. When the platen occupiesthis position, the carriage is in its second or Cap osition and, byreasonof piston rod 1.4 being adjustable, the with respect totheprinting characters can bottom wall of dash pot 16 operates as a stop toalways arrest the movement of. the carriage in the same position.releasing of the pressure on the shift lever 41 spring 43 forcescarriage 1 to initial position, this operation beinglassisted. by redtioned upon .tractile spring 44 interposed between link 31 .and theframe of the machine at 4 5 and retractile spring 46 secured to arm 47posirock shaft 34 and adjusting screw 48 extending from the frame.

Shift lever 24 in the present instance being designated as Fig. key, isadapted upon the application of pressure thereon .to engage with movableabutment 37 and through the connections with the carriage 1, ashereinbefore explained with reference to shift lever 41, to cause amovement thereof, and simultaneously with this movement,

arm 27 of shift lever'24 by means of link 26 and bell crank lever 28operates to slide cam' ,20 allowing cam roller 18 of dash pot 16 totravel along cam face 49 of said sliding cam 20, thereby permitting dashpot 16 to swing on its pivot to assume a lower position, the

I motion being arrested upon the engaging of ,cam roller 18 with thehorizontal surface of sliding cam 20. At this instant piston 15 isapproaching the bottom of dash pot 16,

the imprisoned air therein operating to cushion the arresting ofmovement thereof by the bottom of said dash pot.-

It will be seen that the carriage 1 has thus been shifted to a thirdposition. During this operation the piston 8. connected to double rockerarm location of the carriage Upon the scription the actuating meansabove described will cause piston 8 to engage with the bottom wall ofdashpot 9., the imprisoned air therein operating to silently arrest suchmovement.

Although it will be apparent that I may perforate the piston or employany suitable means whereby the imprisoned air may escape, I have, 'inthe present instance,'constructed the pistons 8 and 15 to fit loosely intheir respective dashpots in order that the said imprisoned air mayslowlyescape during the operation ,of arresting the movement of thecarriage in either direction, thereby allowingsaid pistons to engagethebottom walls of dashpots 9 and 16, respectively, such engagement, ashereinbefore described, determining the position ofthe carriage with re;

spect to the printing devices carried by the A type bars.

Shift key lock 50 is pivotally mounted upon stud 51 extendingfrom theframe of the machine and is provided with a cam face 52 adapted whensald lock is swung on its pivot 51 to engage either of spurs 53 or 54 ofshift levers 24 and 41, respectively,.to maintain either lever in itsdownward position, thereby"- holding the carriage 1 in either of itsshifted? positions.

' While I have, in the present case, described shift lever 41 as the Caplever and shift lever 24 as the Fig. lever, it is obvious that thisarrangement is merely arbitrary and such arrangement may be reversed. Itwill be also understood that while 1 preferably employ a verticallyreciprocating carriage with my shifting devices, the same may beadaptedwith equal efficiency to a different arrangement, 1n which thecarriage is fiXed against vertical movement, the several groups ofprintingdevices comprising the type basketbeing arranged to. reciprocatevertically. p I The operation of my invention, which should be largelyobvious from the above deis substantially. as follows: Pressure on shiftlever 41 will, through the connectin means hereinbefore specificallydescribe cause a from initial position to the second position,- and themovement thereof will be arrested the air cushion operating upon piston15. When,-however, pressure is applied to shift lever 24, theaboveoperation is repeated and simultaneously therewith link 26connected .to shift lever 24 causes sliding cam 20 through the operationof hell crank lever 28, to be'withdrawn from under dashpot 16, allowingthe same to assume a lower position, and conse uently permitting-afurther movement of t e carriage, the air cushion, as before,- cush-.ioning the descent thereof. The aircushion movement of the carriage"aims carriage shifting mechanism wherein the objects ofmy-invention areattained, characterized by, simplicity, and vefiiciency and one in whichconcussion or impact of moving parts has been to a great extenteliminated, and wherever parts are-brought into contact one with anot erthe roduc-tion of'noise is prevented by the emp oyment of a cushion.

While I have shown and described my in-' vention in connection witha-typewr iting ma- :chine of the above type, I do not wish to beunderstood as limiting myself exclusively to that t ;pe alone, as it isadapted as to manyof its eatures to other types of machines, although ofpeculiar value in therelation shown. r

As many changes could I be'made in the above construction and manyapparently widely different embodiments of my invention could be madeWithout departing from the scope, thereof, I intend that all mattercontained in the above description or'shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense,{desire it also to be understood that" the language used in thefollowing claimsis intended to cover all of the generic and speci'ficfeatures of the invention hereindescribed and all statements of thescope 0f the invention, which as a matter of language, might be said tofall therebetween.
